Galveston Island Electric Power Network for Multi-Hazard Resilience Assessment

Intermediate files derived from the Galveston Island electric power distribution network dataset published by Darestani et al. (2022). The collection includes shapefiles and CSVs representing a network of approximately 16,000 utility poles, used for fragility and recovery simulations in a companion paper by Amini et al. (2025). These datasets were established by the NIST Community Resilience Center of Excellence as a testbed for assessing infrastructure resilience against hurricane-induced hazards.

Use Cases

• Wood-pole fragility analysis under combined wind, surge, and wave loading based on per-pole properties.
• Connectivity-based outage analysis via fault tracing to the nearest protective device based on the network graph.
• Crew-dispatch recovery modeling with PageRank-based component prioritization based on Monte-Carlo samples of pole damage states.
• Multi-hazard damage assessment and mitigation optimization for interdependent infrastructure systems based on the Galveston testbed framework.

Strengths

• Represents a detailed distribution-level electric power network comprising approximately 16,000 utility poles.
• Includes multiple data types (shapefiles, CSVs) supporting a full analysis pipeline for multi-hazard assessment.
• Part of a comprehensive testbed with companion code and additional datasets covering built, natural, and social systems.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last update was 2026-04-20 14:52:50.
